FRIDOLIN SCHIFFERLE, OF ST. LOUIS, MISSOURI.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 649,11 1, dated May 8, 1900.

Application led August 9, 1899.

To all whom, it may concern:

Be it known that I, FRIDOLIN SCHIFFERLE, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Water-Heaters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in water-heaters; 'and it consists in the novel construction and arrangement of parts more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure l is a top plan of the heater.' Fig. 2 is a middle vertical 1ongitudinal section taken through the casing, the burner being shown in elevation, the casing and burner being, however, both broken away. Fig. 3 is a horizontal section on line 3 3 of Fig. 2, showing the section of the entire casing and top plan of the entire base of the burner. Fig. 4 is a top plan of the airinlet flue, showing the upper end of the gaspipe and centering-plate through which the pipe projects, the burner valve-casing being removed. Fig. 5 is a side elevation of the centering-plate and upper end of the pipe passing through-it, the air-inlet flue being shown in section; and Fig. 6 is a side elevation of the heater shown submerged within a tub of water, the walls of the tub being shown broken away.

The object of my invention is to construct a heater which is portable and which can be partially submerged within a vessel, tub, or tank of Water, the heat from the casing of they heater gradually raising the temperature of the water to any desirable degree.

In detail the invention may be described as follows:

Referring to the drawings, l represents a hollow casing or drum of any convenient shape or configuration, the same being provided with au air-inlet flue 2 at one end and an outlet-flue 3 at the opposite end. Within the casing l and relatively in a plane below the bases of the flues 2 and 3 is coniined a gas or vapor burner 4, of any of the prevail- Serial No. 726,679. (No model.)

ing forms, the burner being supported above 5o the floor-casing by legs or knobs 5 to allow for the free circulation of air about the pipes of the burner. Leading to the burner-pipes is a gas-supply pipe 6, which passes through the inlet-flue 2 and is centrally1 disposed and held therein by a centering-plate 7, through an opening of which the upper end of the pipe projects. The plate 7 is provided with perforations or openings 8 for the free passage of air therethrough into the interior of the casin g. Coupled to the upper projecting end of the pipe 6 is the valve-casing 9 of the ordinary Bunsen-burner type, to the nozzle ofl which is adapted to be coupled any gas tube or hose l0, leading to any gas-fixture. (Not shown.) The centering-plate 7 is suspended Within the flue 2, from the upper edge of the latter by means of arms 11, which hook over the said edge, as best seen in Fig. 5. In this way the plate may be readily removed and replaced should occasion arise to make repairs tothe heater. The iiues 2 and 3 are substantially equal as to height, and when the heater is submerged the upper ends of the fines are allowed to remain above the waterline, as best seen in Fig. 6, in which 2O represents a tub of ordinary construction. The gas is turned on by the cock or valve 9' and lighted over the burner-pipes by inserting a lighted stick into the casingthrough the iiue 3.

While I have here shown a gas-burner confined within the casing, I do not limit myself thereto, as any other form of burner would answer the same purpose, such as gasolineburners and the like. Neither do I wish to be confined to the precise form of the casing, as any suit-able shape will answer the same purpose.

Having described my invention, what I claim is= Awater-heater comprising a hollow casing, an air-inlet, and an escape-Hueleading from the same, a burner confined within and supported a suitable distance above the bottom of the casing, and located in a plane relatively below the bases of the aforesaid flues, a gas-supply pipe projecting from the heater through the air-inlet flue, a detachable centering-plate holding said pipe in position, the centering-plate, the parts operating substanplate being perforated around the pipe for the tially as and for the purpose set forth.
